Hi,

OCFS is a cluster filesystem so running two mysqld over the same OCFS directory is exactly the same as running two mysqlds over the same directory in a local filesystem on the same machine which is strictly prohibited. If you decide to consider mysql clustering over ocfs please keep in mind thad you don't really need cluster filesystem for mysql clustering. mysql clustering doesn't share disk storage. Considering they use ocfs they may also be mistaken about the difference between mysql and oracle clustering. Oracle cluster requires shared storage whereas mysql does not.

Thanks, Michael

http://dev.mysql.com/doc/refman/5.1/en/multiple-servers.html describes the pitfalls of running multiple servers on the same machine about halfway down the page in the bold 'Warning' paragraph.
